Students will learn how to divide integers. They'll start by using the Algeblocks Quadrant Mat. Students will practice solving both word problems and mathematical ones. Here's an example word problem. Conclude by having your students play the second variant of this game.
Concude by giving your students this challenge:
In this problem, every line is horizontal or vertical, and every line is unique. If there are 2 horizontal lines, and 2 vertical lines, then there are 4 crossings. If there are 3 horizontal lines, and 2 vertical lines, how many crossings are there? If there are at least 2 horizontal lines, and 7 lines in total, what is the least number of crossings? the most? Can you find all possible crossings with 7 lines? Can you find the least/greatest number of crossings for 10 lines? 15? 50? any number of lines?
